Damage behavior of concrete face slab for rockfill dam under the action of high frequency and large amplitude reservoir water circulation
Description
The dataset in File 1 comprises 16 combinations of orthogonal experimental parameters, which are divided into 12 sets of random training samples and 4 sets of validation samples.File 2 dataset compares the extreme value changes of panel damage and the evolution laws of damage extreme values under different reservoir water cycle periods and amplitudes.The dataset in Document 3 represents the evolution law of the proportion of various damage degree units in the lower panel of the reservoir water cycle.The file 4 dataset shows the evolution process of the proportion of damaged units on the panel under different reservoir water cycle periods.The file 5 dataset shows the evolution process of the proportion of damage units on the panel under different amplitudes of water circulation in the reservoir.

This study examines damage evolution behavior of face slab under action of circulating water pressure. A simulation method for cumulative damage was developed by integrating concrete plasticity cumulative damage model (CDP), the Duncan-Chang E-B model, and a frictional interface model. A jump-type accelerated simulation method for reservoir water level fluctuation loading was developed based on the Fourier series. In addition, radial basis function (RBF) neural network was employed to establish parameter identification method for the concrete damage model. Based on the proposed method, this paper examined cumulative damage of the face slab under reservoir water fluctuations condition and investigated influence of fluctuation characteristic.
